Former President George H.W. Bush has been hospitalized at the Houston Methodist Hospital since Saturday after he experienced a shortness of breath, according to his spokesman on Wednesday.
Bush's spokesman Jim McGrath told Reuters in an email that "[Bush] has responded very well to treatments ... Doctors and everyone are very pleased, and we hope to have him out soon."
"He's there. He's fine and he's doing really well," Bush's chief of staff, Jean Becker, said.
Bush, 92, is the father of former President George W. Bush and former Florida Governor Jeb Bush, a 2016 contender for the Republican presidential nomination.
This is the third time that the elder Bush has been hospitalized since 2014, according to Reuters.
He has used a wheelchair in his later years and was hospitalized twice in 2014, once for seven weeks with pneumonia and again for breathing difficulties. In July 2015, he broke a bone in his neck in a fall at the family home in Maine.
Bush's public appearances have been rare since he entered his 90s. Sitting in his wheelchair, wearing a brace on his neck and clad in a Houston Astros jersey, he tossed out the first pitch at the team's playoff game against the Kansas City Royals in October 2015.
In 2016, he marked the 75th anniversary of Japan's attack on Pearl Harbor by attending a ceremony at his library at Texas A&M University, where Bob Dole, the former Republican senator from Kansas, received an award for public service.
